Bespoke and Arched Secondary Glazing
Here to help
Secondary glazing solutions are available for any window, making them suitable for nearly all property types.
Secondary glazing is a discreet solution suitable for both domestic and commercial properties. It can increase heat insulation by up to 65% and reduce noise by up to 80%, all while maintaining the window’s original appearance.
Standard and bespoke shapes:
We supply bespoke secondary glazing for a variety of window shapes, including arched, bay, curved, and circular designs. Stained glass, leaded lights, and historic glass can also be secondary-glazed.
Many windows in older, more traditional properties are out of square. Standard secondary glazing can usually be installed by shaping the timber sub-frame and using bespoke windows with matching finishing trims.
Our experience with church and historic building renovations provides access to a wide range of styles and templates, which we can modify to help minimise costs.
Specialist glass, tints, and colours:
We offer specialist glass options for enhanced security, noise reduction, and solar protection. A full range of glazing thicknesses and treatments is available to customise thermal, acoustic, and security performance. Frames and special paint finishes are offered in 200 RAL colours.
Superior Aluminium:
We use slim, strong aluminium profiles that maintain structural integrity under heavier loads, making them suitable for large window applications.
Our bespoke secondary windows preserve the original character of existing windows while incorporating modern design, materials, and production techniques.
- Noise, cold, security, and condensation issues are managed and controlled.
- We offer a range of design options, including historical, contemporary, and unique styles, with 200 frame colours and lift-out panels available.
- Multiple glazing options.
- 10 Year Guarantee for all frames and glazing.

A very personal service; I felt valued as a customer and they listened to what I wanted. Excellent quality of product and service. I decided not to go with a larger well-known brand as they did not provide the same personal service in the quotation stage.

Excellent service from start to finish, we had secondary Glazing fitted into our dental practice. Glevum attended when they said they would, completed the job with minimum disturbance to the daily running of the practice, and left their work place clean and tidy. The glazing has made such a difference, staff are much warmer and the radiators have been turned to low.

Glevum were prompt in quoting for the work. The order was placed and doors and windows far more quickly than other companies were able. The fitting was completed to a high standard. I'm very happy with the work and product!!
